Oh tnx! this video is unknown to me and it enlightened me, around 17.20 when he goes to the ride it continues to chick the hi-hat and along whole song it stops the stick over the snare and, I've tried now, it produces that stopped sound letting vibrate the snare wire.
Yesterday I've recorded a demo using a 14x6,5 DW snare drum with a puresound wire and a loose batter head and the sound is much closer to the Pick's sound.
I think that will be my way when I must choose my new snare drum... when I Play DS, for other purposes I've other 2 snares, also he could used something like this
